The IOCTL_AACS_GET_CERTIFICATE request corresponds to the step of the Advanced Access Content System (AACS) authentication algorithm (AACS-Auth) in which the drive provides its certificate and nonce to the host. For a complete description of AACS-Auth, see the Advanced Access Content System, Introduction and Common Cryptographic Elements specification that is published by Advanced Access Content System Licensing Administrator (AACS LA).
